.PAY domain
Checking availability…
.PAY is a branding and relevance signal, not an automatic SEO ranking boost. Use it when it improves payment-page clarity and user trust, then follow normal SEO practices. Start by securing or pre-ordering the domain at domain.pay: https://domain.pay/register.
Cloud load balancers are usually referenced by hostname, so you point the apex of mcmail.pay using an ALIAS/ANAME record (or a CNAME on a subdomain) at the balancer's DNS name. This lets the balancer's IPs change without breaking mcmail.pay. Your provider documents the exact target.
During LRP1, .PAY eligibility is limited to registrants that conduct payment transactions online using an approved Payment Service Provider or third-party payment processor, with payment-related use. For registration help, use domain.pay: https://domain.pay/register. Separate financial licensing depends on your activity and jurisdiction.
Premium mcmail.pay names follow the same .PAY eligibility and validation expectations as standard names; the difference is usually pricing rather than who may register. The registry's payment-related focus still applies. domain.pay shows premium status and pricing at https://domain.pay/pricing.
A .PAY pre-order can fail if the name is registered earlier, classified as premium, reserved, blocked, refused by registry policy or lost to another faster submission. Search and order through domain.pay: https://domain.pay/domains, and review its credit/cash-refund options.
Availability is checked live and re-verified before payment. Pre-orders are first-day registration attempts — registration is not guaranteed; 100% credit toward another domain (or 80% cash refund) if unsuccessful.
